[Tex/LaTex] Setting the height of subfigure

subfloats

I want to include two subfigures in one figure.

I tried the following MWE. It works but I can't find out how to define the height of the subfigures (keeping their aspect ratios) without changing the width of the subcaptions.

\documentclass{memoir}
\usepackage{graphicx}

\newsubfloat{figure}

\begin{document}

\begin{figure}
  \begin{center}
    \begin{minipage}{\textwidth}
      \subbottom[A figure.]{\includegraphics[width=\textwidth]{file1}}
    \end{minipage} \\
    \begin{minipage}{\textwidth}
      \subbottom[Another figure.]{\includegraphics[width=\textwidth]{file2}}
    \end{minipage}
    \caption{Example of two figures.}
  \end{center}
\end{figure}

\end{document}

P.S.: How do I write MWEs that include graphics at TeX.SX? Without the included files, it isn't really a working example.

Something like this?

The trick here is to put the full width minipage inside the sub-figure, so that the caption width is \textwidth, and to then set the horizontal alignment within each such environment:

\documentclass{memoir}
\usepackage{graphicx}

\newsubfloat{figure}

\begin{document}

\begin{figure}
  \centering
   \subbottom[A figure.]{%
     \begin{minipage}{\textwidth}
       \centering
       \includegraphics[width=\textwidth, height=10mm, keepaspectratio]{example-image-a}
     \end{minipage}%
   }\\
   \subbottom[Another figure.]{%
     \begin{minipage}{\textwidth}
       \centering
       \includegraphics[width=\textwidth, height=5mm, keepaspectratio]{example-image-b}
     \end{minipage}%
   }
    \caption{Example of two figures.}
\end{figure}

\end{document}

Note that \centering is better here than the center environment as the figure environment already introduces vertical space and we don't want the additional space which center includes.

Note that I've used example-image-a and example-image-b which are included in the mwe package and so everybody with a full TeX installation has them. (You don't need to load the package for the images to be available - they are deliberately installed so that they may be freely used. See the mwe package for additional images available in a variety of dimensions, formats, shapes and sizes.)

[Tex/LaTex] Multiple subfigures using the subfigure environment

You're doing contradictory requests: you're allowing .2\linewidth (about 69pt) for the subfigures, while you want them 4cm wide (about 114pt).

Look at the following example (I've used \test instead of your \input just for showing the results with the demo option to graphicx)

\documentclass{report}
\usepackage{subcaption}
\usepackage[demo]{graphicx}
\usepackage{tikz,pgfplots}

\newcommand{\test}{\includegraphics[width=\figurewidth,height=\figureheight]{x}}

\newlength\figureheight 
\newlength\figurewidth 

\begin{document}

\begin{figure}
\centering
\begin{subfigure}{.3\linewidth}
  \centering
  \setlength\figureheight{\linewidth} 
  \setlength\figurewidth{\linewidth}
  \test \caption{Fig 1}
\end{subfigure}%
\hspace{1cm}%
\begin{subfigure}{.3\linewidth}
  \centering
  \setlength\figureheight{\linewidth}
  \setlength\figurewidth{\linewidth}
  \test \caption{Fig 2}
\end{subfigure}\\
\vspace{1cm}
\begin{subfigure}{4cm}
  \centering
  \setlength\figureheight{4cm}
  \setlength\figurewidth{4cm}
  \test \caption{Fig 3}
\end{subfigure}
\begin{subfigure}{4cm}
  \centering
  \setlength\figureheight{4cm}
  \setlength\figurewidth{4cm}
  \test \caption{Fig 4}
\end{subfigure}
\end{figure}
\end{document}

In the first row the squares fill all the space available (\linewidth refers to the current linewidth, inside a subcaption environment it's what you reserved to it) and they are separated by a 1 cm space (notice the % comments to mask off the end of lines). In the second row the squares are 4cm wide, separated by a normal interword space.

You don't need to specify (a) and so on in the captions, as they are provided automatically.

[Tex/LaTex] Remove (a), (b) from subfigure numbering, but keep the subfigure caption

Just stack the subcaption text under the subfigure. You can change the fontsize of the subcaptions just by changing the \footnotesize to the desired size. The gap between figure and caption is controlled by the optional argument to \stackunder and is, in this example, set to 5pt (the default is 3pt).

Note that the subcaptions in this technique, will not automatically word-wrap. In your case, there was no need for wrapping, since they were short labels. If wrapping were needed, the last argument to \stackunder could be a \parbox.

I further assumed, that since you wished to remove the (a), (b), that you had no desire to separately reference the individual subfigures. You can still reference the overall figure with \ref{}.

\documentclass{article}
\usepackage{stackengine}
\usepackage[demo]{graphicx}
\begin{document}
\begin{figure}
\footnotesize
\stackunder[5pt]{\includegraphics[width=2in,height=.7in]{fileA}}{MRI-CGCM3}%
\hspace{1cm}%
\stackunder[5pt]{\includegraphics[width=2in,height=.7in]{fileB}}{NorESM1-M}
\caption{November to April}
\end{figure}
\end{document}
